This query was originally published in the threat analytics report, Operation Soft Cell.
Operation Soft Cell is a series of campaigns targeting users' call logs at telecommunications providers throughout the world. These attacks date from as early as 2012.
Operation Soft Cell operators sometimes use legitimate web server processes to launch commands, especially for network discovery and user/owner discovery. The following query detects activity of this kind.

LemonDuck is an actively updated and robust malware primarily known for its botnet and cryptocurrency mining objectives. First discovered in 2019, LemonDuck has since adopted more sophisticated behavior and escalated its operations in 2021. Today, beyond using resources for its traditional bot and mining activities, LemonDuck steals credentials, removes security controls, spreads via emails, moves laterally, and ultimately drops more tools for human-operated activity.
